Patent JP-H03208375-A (JP)
Title: Semiconductor pressure sensor
Inventor: ISHIBASHI KIYOSHI
IPC: G01L9/04
Filed: 1990-01-10
Abstract: PURPOSE:To facilitate the temperature compensation by an outer circuit thereby enabling the pressure measurement not affected by ambient temperature to be performed with high precision by a method wherein the boron impurity concentration is evenly increased in the depth direction of a gauge resistor. CONSTITUTION:A gauge resistor 3 is formed by implanting boron ions through a window made by photolithography in a thermal oxide film 2 formed on the surface of an N type silicon semiconductor substrate 1. At this time, the boron ions are implanted at the implantation accelerating voltage continuously or dispersively changed from several scores of KeV to a hundred and several scores of KeV, and the gauge resistor 3 evenly increases the boron impurity concentration (a) in the depth direction (b). Since most of the current running in the gauge resistor 3 runs in the part containing the evenly increased boron impurity, the resistance value of the gauge resistor and the temperature characteristics are dominantly affected by this part. Through these procedures, the temperature characteristics of the gauge resistor 3 can be approximated to almost linear prospective temperature characteristics by the silicon semiconductor in even boron concentration thereby enabling the temperature compensation by the outer circuit of a silicon semiconductor pressure sensor to be performed with high precision.

IPC: H01L21/331
Filed: 1985-01-09
Abstract: PURPOSE:To improve the emitter-base reverse yield voltage by reducing the curvature of the emitter-base junction plane in the periphery of an emitter region, by a method wherein the emitter region is formed in the semiconductor substrate from a region isotropically etched through an aperture of the insulation film provided over one main surface of the semiconductor substrate. CONSTITUTION:Isotropic etching is carried out through an aperture 3 bored in the insulation film 2 provided over one main surface of the semiconductor substrate 1, and an emitter region 7 is formed from this etching region to the substrate 1. For example, an Si semiconductor substrate 1 is isotropically etched through an aperture 3 bored in an SiO2 film 2 covering the Si substrate 1, and an emitter region 7 is formed by diffusion. A base region 5 is formed deeper with the etching depths of the Si substrate. Since this process can improve field concentration in the periphery of the emitter region by reducing the curvature the periphery of the emitter region, the emitter-base reverse yield voltage can be improved.

Title: Controller of reactive power
Inventor: MASUI HISASHI
IPC: H02M7/48
Filed: 1983-01-08
Abstract: PURPOSE:To suppress the fluctuation of the reactive power and to limit the fluctuation of the output voltage of a flywheel generator within a fixed range, by combining a phase advance capacitor and a reactive power generator consisting of a self-oscillation type voltage inverter. CONSTITUTION:A flywheel generator 1 is driven to apply breakers 2 and 3, and a thyristor converter 5 is controlled. Thus the lagging reactive power is generated when a desired current is supplied to a load coil 6, and the output voltage of the generator 1 has fluctuation. At the same time, the apparent capacity of the generator 1 is also increased. Then a self-oscillation type inverter 22 is controlled to compensate the fluctuation of the reactive power. A reactive power generator consisting of a transformer 21, the inverter 22 and a smoothing capacitor 23 can produce both phase advance and phase delay type reactive power. Thus it is possible to compensate a wide range of fluctuation of the reactive power by combining a phase advance capacitor 20 and the reactive power generator.

Title: Stabilizing and strengthening work for soil
Inventor: IWASAKI TAKAAKI
IPC: C09K17/30
Filed: 1980-01-11
Abstract: PURPOSE: To stabilize and strengthen soil to provided the stabilized soil with a high strength, an adequate elasticity, and a long-lived durability by mixing a specific powdery urethane polymer in a wet soil and solidifying it.  
     CONSTITUTION: A powdery urethane polymer having two or more NCO groups on its terminal and a quaternary ammonium salt in its molecular chain is mixed in a wet soil and the wet soil is solidified. The powdery urethane polymer used can be advantageously used provided that it is covered with a filler prior to use because it can be easily covered with a filler simply by being mixed with the filler by the reason that the amount of the powdery urethane polymer to be used can be lessened. Although moisture-rich soil can be sufficiently solidified by the use of a rather larger amount of the said urethane polymer, the combined use of the urethane polymer with a solidifying assistant and an inorganic hydraulic compound is more effective for solidification of wet soil.

IPC: G01N31/00
Filed: 1984-01-10
Abstract: PURPOSE:To pick up a gas including SO3 efficiently, by including halogenated pitassium salt or the like in a honeycomb shaped molding, and using it. CONSTITUTION:Exhaust gas 1 is introduced to a sampling tube 2, which is arranged in a flue 10 as a sampling gas. Part of the gas is guided to an analyzer 7 through a honeycomb shaped molding 3, on which halogenated potassium or the like is carried. The remaining part is guided to another analyzer 5 through a sampling tube 4. When the exhaust gas passes the molding 3, SO3 included in the gas reacts with the halogenated potassium or the like carried on the molding 3 and yields halogenated hydrogen. At this time, when the temperature of the exhausted gas is lower than about 300-400 deg.C, the gas temperature is increased by a heater 6. The concentration of the SO3 included in the exhausted gas 1 can be obtained from the difference between the measured values of the concentrations of the halogenated hydrogen, which are measured by the analyzers 7 and 5.

Title: Controller for converter
Inventor: MATSUSHITA TOMOYUKI
IPC: H02J3/24
Filed: 1991-01-14
Abstract: PURPOSE:To stably operate an AC system and converter by detecting the hunting of a control system and automatically changing the gain of the control system. CONSTITUTION:The variation of the hunting of a control system is detected by means of a primary delay circuit 17 and adder circuit 18. When it is discriminated that the hunting becomes larger than a set value by means of level detection circuits 19 and 20, monostable multivibrators 21 and 22 are actuated. In case the hunting continues and the set time of a timer circuit 24 has elapsed during the time of the circuits 21 and 22, a signal is inputted to a reactive power decision circuit 14 and the gain of the control system is lowered. Therefore, even when the hunting occurs due to a decrease in the ground capacity caused by the accident of an AC system or a change in the status of a load, stable operation can be maintained by lowering the gain of the control system.
